Alright, im presuming that the gear isnt composited, but ill mentioned that
First, Kamek's disabling sounds a lot like Power Null, which NoLegs resists via the fact Syphon exists in EBF5 (which does the exact same thing as whats seen in the video, disables magic) (Gear is Wizard Hat, Cardboard Box, and Wizard Robe), so he should be fine on that front. Hell, NoLegs doesnt really need to use Scan, seeing how spellcasters are common
Also, if he Defends using Shell Armor (or summons a Angel Mirror), he becomes Enchanted- making him weaker to physical strikes, but totally immune to magic for as long as the effect is up. Transmutation seems to be magic based sooooo
Basically, to NoLegs, Kamek is just yet another caster enemy and will either apply Syphon on Kamek (forcing him to go in close, which is where NoLegs can cut him up), or apply Enchanted on himself.....which would achieve the same thing
TLDR: NoLegs resists funny magikoopa BS and can shut Kamek down easily
